[0055] The present invention provides an air conditioner indoor unit 100, which can be divided into various types such as a wall-mounted air conditioner indoor unit horizontally hung on a wall, a floor-standing cabinet-type air conditioner, and a ceiling-mounted air conditioner installed on a ceiling. Among them, when the air outlet of the air conditioner indoor unit 100 is usually set relatively close to the user, the wind feeling is obvious. Therefore, an air conditioner indoor unit 100 with a no-wind feeling mode is required.

[0056] Please refer to Figure 1 and Figure 2 , in an embodiment of the present invention, the air conditioner indoor unit 100 includes:

[0057] A housing 10, the housing 10 having an air outlet 10a; and

[0058] An air deflector assembly 30, the air deflector assembly 30 being rotatably disposed at the air outlet 10a. The air deflector assembly 30 includes an outer air deflector 31 and an inner air deflector 33. The inner air deflector 33 is provided with a plurality of air dispersion holes 33a. The outer air deflector 31 is provided with a receiving space 40. The inner air deflector 33 is at least partially located in the receiving space 40. When the inner air deflector 33 is in the open position, the inner air deflector 33 is at least partially exposed outside the receiving space 40, and the plurality of air dispersion holes 33a communicate with the air outlet 10a; and / or when the inner air deflector 33 is in the retracted position, the inner air deflector 33 is received in the receiving space 40.

[0059] Specifically, the housing 10 has an air outlet 10a, and the air deflector assembly 30 is rotatably disposed at the air outlet 10a. The outer air deflector 31 and / or the inner air deflector 33 can be rotatably disposed at the air outlet 10a. For example, the outer air deflector 31 is rotatably connected to the housing 10, and then the inner air deflector 33 is disposed on the outer air deflector 31; or the inner air deflector 33 is rotatably connected to the housing 10, and then the outer air deflector 31 is disposed on the inner air deflector 33; or the outer air deflector 31 and the inner air deflector 33 are simultaneously rotatably connected to the housing 10, and the rotation connection method is a hinge or a shaft rotation connection. As long as the rotation connection method can be realized, it is within the protection scope of this patent.

[0060] In Figure 1 and Figure 2In it, the air outlet 10a extends along the horizontal direction, and the extending directions of the outer air deflector 31 and the inner air deflector 33 are the same as that of the air outlet 10a, that is, both are in the horizontal direction. The inner air deflector 33 is provided with a plurality of air-diffusing holes 33a, and the opening sizes of the air-diffusing holes 33a can be set as required. The outer air deflector 31 is provided with a receiving space 40, at least part of the inner air deflector 33 is located in the receiving space 40, and at least part of the inner air deflector 33 is exposed outside the receiving space 40 and is in the open position. At this time, the air conditioner indoor unit 100 realizes the draft-free mode, and the plurality of air-diffusing holes 33a communicate with the air outlet 10a. When the draft-free mode is not required, the inner air deflector 33 can be received in the receiving space 40 and is in the retracted position. The transformation of the inner air deflector 33 between the open position and the retracted position can be manually controlled or an automatic control can be realized by setting a control component, and both are within the protection scope of this patent.

[0061] It should be noted that the switching of the inner air deflector 33 between the open position and the retracted position can be that the inner air deflector 33 is arranged side by side with the outer air deflector 31 along the extending direction of the air outlet 10a, or arranged side by side perpendicular to the extending direction of the air outlet 10a, and both are within the protection scope of this patent. In order to prevent dust from falling into the inner air deflector 33 when the air conditioner indoor unit 100 is in the shutdown state, the inner air deflector 33 is arranged side by side with the outer air deflector 31 perpendicular to the extending direction of the air outlet 10a.

[0062] The air conditioner indoor unit 100 of the present invention includes a housing 10 and an air deflector assembly 30. The housing 10 has an air outlet 10a, and the air deflector assembly 30 is rotatably arranged at the air outlet 10a. By setting the air deflector assembly 30 to include an outer air deflector 31 and an inner air deflector 33, the inner air deflector 33 is provided with a plurality of air-diffusing holes 33a, and the outer air deflector 31 is provided with a receiving space 40. At least part of the inner air deflector 33 is located in the receiving space 40. When the air conditioner indoor unit 100 realizes the draft-free function, at least part of the inner air deflector 33 is exposed outside the receiving space 40 and is in the open position. The plurality of air-diffusing holes 33a communicate with the air outlet 10a, and the air flow blown out through the air outlet 10a will not directly blow on the user, so that the comfort of the air conditioner is high. When it is not necessary to turn on the draft-free function of the air conditioner indoor unit 100, the inner air deflector 33 is received in the receiving space 40 and is in the retracted position to prevent dust from accumulating on the inner air deflector 33 and meet the user's needs at the same time.

[0063] Please refer to Figures 7 to 9 , in one embodiment, the outer air deflector 31 includes:

[0064] A first air deflector 311, the first air deflector 311 extends along the direction of the air outlet 10a, and the first air deflector 311 has a left side 3111 and a right side 3113 which are oppositely arranged; and

[0065] The second air guide plate 313 extends along the direction of the air outlet 10a, and has a first side edge 3131 and a second side edge 3133 that are relatively arranged, the first side edge 3131 is connected to the left side edge 3111, and the second side edge 3133 is spaced apart from the right side edge 3113, and the accommodating space 40 is formed between the first air guide plate 311 and the second air guide plate 313.

[0066] It can be understood that the first air guide plate 311 and the second air guide plate 313 are both arc-shaped plate structures, which are convenient for processing. The first air guide plate 311 is arranged close to the air outlet 10a, and a plurality of mounting holes 31a are provided on the first air guide plate 311. A louver (not shown) is provided on the side of the first air guide plate 311 away from the inner air guide plate 33 through the mounting holes 31a to achieve air outlet in multiple directions.

[0067] The first air guide plate 311 has a left side 3111 and a right side 3113 that are relatively arranged, and the second air guide plate 313 has a first side 3131 and a second side 3133 that are relatively arranged. The first side 3131 is connected to the left side 3111, and the connection method can be a fixed connection or a detachable connection, such as fixing the first side 3131 and the left side 3111 by gluing or welding, or detachably connecting them by buckles and screws. The second side 3133 is spaced apart from the right side 3113, so that there is a certain gap between the first air guide plate 311 and the second air guide plate 313, so that the inner air guide plate 33 can be accommodated in the accommodation space 40.

[0068] Please refer to Figure 8 and Figure 9 One of the outer air guide plate 31 and the inner air guide plate 33 is provided with a guide groove 315, and the other one is provided with a protrusion 331. The outer air guide plate 31 is slidably connected with the inner air guide plate 33 through the cooperation between the protrusion 331 and the guide groove 315.

[0069] In this embodiment, in order to achieve that there is no position deviation when the outer air guide plate 31 and the inner air guide plate 33 rotate, a guide groove 315 is provided on the inner side of the outer air guide plate 31, and a protrusion 331 is provided on the inner air guide plate 33. The protrusion 331 can be located on the inner surface or outer surface of the inner air guide plate 33, or a protrusion 331 is provided on the inner side of the outer air guide plate 31, and the inner air guide plate 33 is provided with a guide groove 315. The smooth rotation of the outer air guide plate 31 and the inner air guide plate 33 is achieved through the cooperation of the guide groove 315 and the protrusion 331.

[0070] Further, in order to meet the needs of different users, when the air conditioner indoor unit 100 is in working state, the inner air guide plate 33 is in the retracted position and rotates simultaneously with the outer air guide plate 31 to open the air outlet 10a;

[0071] Alternatively, when the inner air guide plate 33 is in the open position, the outer air guide plate 31 and the inner air guide plate 33 jointly cover the air outlet 10a.

[0072] In this embodiment, when the air conditioner indoor unit 100 is in the working state, the inner air guide plate 33 has two positions, an open position and a retracted position. When the inner air guide plate 33 is in the retracted position, the inner air guide plate 33 and the outer air guide plate 31 rotate simultaneously to open the air outlet 10a. At this time, the air conditioner does not turn on the function of no wind feeling. When the inner air guide plate 33 is in the open position, the outer air guide plate 31 and the inner air guide plate 33 jointly cover the air outlet 10a. At this time, the air conditioner turns on the function of no wind feeling.

[0073] In addition, when the air conditioner indoor unit 100 is in the shutdown state, the inner air guide plate 33 is in the retracted position, and the outer air guide plate 31 covers the air outlet 10a. The inner air guide plate 33 is received in the accommodation space 40 to prevent dust from falling on the inner air guide plate 33 when the air conditioner indoor unit 100 is not in use, so as to reduce the cleaning difficulty.

[0074] Furthermore, please refer to Figures 3 to 12 , the air conditioner indoor unit 100 further includes a rotating assembly 50 provided on the outer air guide plate 31. The inner air guide plate 33 is provided on the rotating assembly 50, and the rotating assembly 50 is rotatable relative to the outer air guide plate 31.

[0075] In this embodiment, since the rotation between the outer air guide plate 31 and the inner air guide plate 33 is frequent, after the number of rotations between the two reaches a certain amount, the rotation may not be smooth enough. In order to improve the service life of the inner air guide plate 33 and the outer air guide plate 31, a rotating assembly 50 is provided on the outer air guide plate 31. The inner air guide plate 33 is provided on the rotating assembly 50, and the rotating assembly 50 is rotatable relative to the outer air guide plate 31. By rotating the rotating assembly 50, the inner air guide plate 33 can be driven to change between the open position and the retracted position. The rotation mode of the rotating assembly 50 can be manual control or electric control by setting a driving mechanism.

[0076] In one embodiment, the rotating assembly 50 includes:

[0077] a base 51, the base 51 is provided on the outer air guide plate 31; and

[0078] a mounting plate 53, the mounting plate 53 is movably connected to the base 51, the inner air guide plate 33 is provided on the mounting plate 53, and the mounting plate 53 is rotatable relative to the outer air guide plate 31.

[0079] In this embodiment, the mounting plate 53 is used to mount the inner air guide plate 33, and the base 51 is used to connect the outer air guide plate 31 with the inner air guide plate 33, and is used to support the mounting plate 53 to improve the stability of the movement of the inner air guide plate 33. The mounting plate 53 is movably connected to the base 51, and the movably connected mode is a rotating connection or a sliding connection or a combination of a rotating and sliding connection, so as to realize the transformation of the inner air guide plate 33 between the open position and the retracted position.

[0080] In the embodiment of the present application, in order to simplify the connection structure, a rotating portion 517 is provided on the base 51, and a rotating groove 533 is provided on the mounting plate 53. The rotating portion 517 is accommodated in the rotating groove 533 to achieve a movable connection between the mounting plate 53 and the base 51.

[0081] The inner air guide plate 33 and the mounting plate 53 may be fixedly connected or detachably connected, such as by gluing or welding or by snaps or screws. For easy installation, in one embodiment, the mounting plate 53 is detachably connected to the inner air guide plate 33. Specifically, a snap groove 531 is provided on the outer side of the mounting plate 53, and the inner air guide plate 33 is provided with a snap (not shown), or a snap is provided on the mounting plate 53, and the inner air guide plate 33 is provided with a snap groove 531. The mounting plate 53 is detachably connected to the inner air guide plate 33 through the cooperation of the snap groove 531 and the snap.

[0082] Please refer to Figure 13 and Figure 14 In order to achieve the precision and accuracy of the automatic rotation opening angle of the inner air guide plate 33, a driving device 55 is provided to realize the rotation between the inner air guide plate 33 and the outer air guide plate 31. The driving device 55 can be a belt drive or a gear drive structure, which is not limited here. The rotating assembly 50 also includes a driving device 55 provided on the base 51, and the driving device 55 is used to drive the mounting plate 53 to rotate and have the open position and the folded position.

[0083] Furthermore, the driving device 55 includes a driving member 551 disposed on the machine base 51, and a transmission assembly 553 transmission-connected to the driving member 551, the transmission assembly 553 includes a transmission member 5531 disposed on the mounting plate 53, and the driving member 551 drives the transmission member 5531 to drive the mounting plate 53 to rotate.

[0084] Since the driving member 551 needs to be powered, in order to ensure its working stability, the driving member 551 is arranged on the base 51, and the relative position between the base 51 and the outer air guide plate 31 does not change. The driving member 551 is a motor, and the transmission member 5531 can be a belt or gear transmission. The driving member 551 drives the transmission member 5531 to drive the mounting plate 53 to rotate.

[0085] Since the mounting plate 53 needs to be rotated frequently during use, in order to make the rotation of the mounting plate 53 smoother and more stable, the transmission member 5531 is slidably connected to the machine base 51 to drive the rotation of the mounting plate 53.

[0086] In one embodiment, in order to ensure the accuracy of the rotation opening angle of the mounting plate 53, the transmission assembly 553 further includes a gear 5533 provided at the output end of the driving member 551. The transmission member 5531 is provided with a rack 5535 that cooperates with the gear 5533. The machine base 51 is further provided with a sliding groove 511. One end of the rack 5535 away from the gear 5533 is slidably connected to the sliding groove 511. The driving member 551 drives the gear 5533 to mesh with the rack 5535 for transmission, so as to drive the rack 5535 to slide in the sliding groove 511. Among them, the gear 5533 is a gear structure in which a driving gear and a driven gear cooperate. The rack 5535 cooperates with the driven gear to ensure that the rotation opening angle of the mounting plate 53 is more accurate, so that there is no interference between the inner air guide plate 33 and the outer air guide plate 31. The rack 5535 is slidably connected to the sliding groove 511 to realize the rotation of the mounting plate 53.

[0087] Further, please refer to Figure 14 , the sliding groove 511 includes a first section 5111 and a second section 5113 that are connected at an angle to the first section 5111. The connection between the first section 5111 and the second section 5113 is smoothly transitioned. The rack 5535 is a straight rack.

[0088] Wherein the first section 5111 and the second section 5113 are arranged at an obtuse angle, and the connection between the first section 5111 and the second section 5113 is smoothly transitioned, ensuring stronger stability when the rack 5535 slides along the sliding groove 511. Since the inner air guide plate 33 is installed on the mounting plate 53, when the mounting plate 53 slides along the sliding groove 511, the rotating part 517 slides along the rotating groove 533. The rotating groove 533 is arranged parallel to the rack 5535, and the rotation stability of the mounting plate 53 is strong.

[0089] To improve the firmness of the connection, the machine base 51 includes a bottom plate 513 and a cover plate 515. The mounting plate 53 is located between the bottom plate 513 and the cover plate 515 and is rotatably connected to the bottom plate 513 and the cover plate 515. The sliding groove 511 and the driving device 55 are spaced apart on the bottom plate 513. The cover plate 515 is provided with an avoidance groove 5151 corresponding to the sliding groove 511.

[0090] In this embodiment, the bottom plate 513 and the cover plate 515 are arranged in parallel, and a receiving cavity for accommodating the mounting plate 53 is formed therebetween.

[0092] In one embodiment, arranging the two driving devices 55 adjacent to the left end plate 317 and the right end plate 319 will not interfere with the air volume of the air outlet 10a. In addition, since the outer air guide plate 31 has a certain length, in order to ensure that the outer air guide plate 31 can approach and move away from the housing 10 more flexibly, preferably there are two driving devices 55, and the two driving devices 55 are respectively arranged adjacent to the left end plate 317 and the right end plate 319 in one-to-one correspondence.

[0093] In another embodiment, in order to reduce the driving force, the farther away from the rotating shaft, the more labor-saving, the two driving devices 55 are arranged on the side of the housing 10 adjacent to the air outlet 10a.

[0094] To avoid the risk of the driving device 55 being directly exposed and damaged, an installation cover 70 is provided to protect the driving member 41. The air conditioner indoor unit 100 further includes an installation cover 70 provided on the outer air guide plate 31. The driving device 55 is arranged in the installation cover 70, and a heat insulation member (not shown) is provided between the installation cover 70 and the driving device 55. Since the outer air guide plate 31 is arranged at the air outlet 10a, the driving device 55 is arranged adjacent to the air outlet 10a. When hot air or cold air is blown out from the air outlet 10a, due to the change in temperature difference, condensation is likely to occur in the driving device 55. The heat insulation member can be a material with heat insulation performance such as sponge or foam to prevent condensation from occurring when the driving device 55 works and improve the safety performance.

[0095] Furthermore, please refer to Figure 4 and Figure 6, the housing 10 includes a chassis 11 and a front frame 13 provided on the chassis 11. An air outlet 10a is formed between the chassis 11 and the front frame 13. The air deflector assembly 30 is rotatably provided on the chassis 11.

The air deflector assembly 30 is rotatably connected to the chassis 11 through the cooperation of the axial hole 31b and the rotating shaft.

[0097] Furthermore, an electric control box is provided on the chassis 11. The air conditioner indoor unit 100 further includes a connecting wire 90 provided between the electric control box and the driving device 55, and the length of the connecting wire 90 is adjustable.

[0098] In this embodiment, since the inner air deflector 33 has an open position and a retracted position relative to the outer air deflector 31, and the inner air deflector 33 is electrically connected to the electric control box through the connecting wire 90 by the driving device 55, and the inner air deflector 33 and the outer air deflector 31 can rotate relative to the chassis 11 simultaneously. In one embodiment, the air deflector assembly 30 can rotate 85° clockwise and 95° counterclockwise relative to the chassis 11. When the air deflector assembly 30 rotates to the position where the distance between the driving device 55 and the electric control box is the farthest, the connecting wire 90 is in an extended state. When the air deflector assembly 30 rotates to the position where the distance between the driving device 55 and the electric control box is the closest, the connecting wire 90 is in a slack state. The length of the connecting wire 90 is adjustable. At least one limiting end (not shown) can be provided on the inner side of the outer air deflector 31 to limit the connecting wire to the outer air deflector 31, or at least one limiting end can be provided on the chassis 11, so that when the connecting wire 90 is in a slack state, it will not be exposed from the air outlet and affect the overall aesthetics of the machine.
